Watering Your San Antonio Lawn Through Stage 2 or Stage 3 Restrictions
Macario Brothers Lawn Care • June 2026 • San Antonio, TX
When SAWS declares Stage 2 or Stage 3 watering restrictions, San Antonio lawns can still survive with proper strategy. The keys are watering on your designated days only, getting maximum penetration in each cycle, mowing higher to reduce evaporation, accepting some summer dormancy as protective rather than damaging, and supporting trees and high-value plants separately within the rules.
If you have lived in San Antonio for more than a couple of years, you have dealt with SAWS watering restrictions. Stage 2 and Stage 3 typically limit lawn watering to once per week on a designated day during specific hours. For homeowners used to twice-weekly deep watering, the change is meaningful. We want to walk through how to keep your lawn alive and reasonably healthy under restrictions.
What Each Stage Actually Means
Stage 2
Allows landscape irrigation one day per week on a designated day based on your address, with watering only allowed during specified early morning and late evening hours. Hose-end watering and drip irrigation have separate rules.
Stage 3
Restrictions are tighter, often limiting watering hours further. Hand watering with a hose may still be allowed but on the same designated day. Drip irrigation usually has slightly more flexibility. Verify the specific rules when restrictions are declared — SAWS publishes detailed rules and they can change between drought events.
Making the Most of Your Designated Day
On your watering day, the goal is maximum penetration. The same one inch per week target that applies in normal conditions still applies, but you have to deliver it in one cycle instead of two.
Rotary Heads
Applying about a third of an inch per hour — run each zone for 2.5 to 3 hours total to hit the one-inch target.
Spray Heads
Applying about three-quarters of an inch per hour — run each zone for 75 to 90 minutes to deliver a full inch.
Cycle and Soak
Split runtime into 30–45 minute cycles with an hour of soak between. Essential in San Antonio's heavy clay soils to prevent runoff. Modern smart controllers do this automatically.
Catch Can Test
Set out 5–8 tuna cans across a zone, run the full cycle, and measure the depth. You want about an inch of total depth to confirm proper delivery.
Mowing Changes Under Restrictions
Raise the Mowing Height
3.5–4 inches for St. Augustine and 2.5–3 inches for Bermuda. Taller cuts shade the soil and reduce evaporation by 30–50% compared to short cuts.
Mow Less Frequently
Slower growth under water stress means the lawn does not need cutting as often. Every 10 to 14 days is typical during heavy restrictions.
Keep Blades Sharp
Stressed lawns are more vulnerable to damage from dull blades. Sharp cuts reduce trauma to already-stressed grass plants.
Mulch Clippings
Return clippings to the lawn to restore moisture and organic matter, reducing stress on the turf during the restriction period.
Accept Some Dormancy
This is the hardest part for many homeowners. Warm-season lawns — Bermuda, St. Augustine, Zoysia — can go semi-dormant under prolonged water stress and recover when conditions improve. The lawn looks tired and somewhat brown during dormancy, but the crowns and roots survive.
Lawns that go dormant gracefully usually green back up within 2 to 4 weeks of restriction lift. Lawns pushed too hard with insufficient water often have more lasting damage than dormant lawns. The mental shift is from green to alive. A brown but living lawn is a successful outcome under Stage 3 restrictions.
Supporting Trees, Drip Zones & Beds
Mature Trees
Mature trees are far more valuable than the lawn and deserve separate attention. Under most restrictions, hand watering trees with a hose or soaker hose remains allowed. For each mature tree — live oaks, post oaks, pecans, and other natives — run a soaker hose at the dripline for 60–90 minutes once a week. Especially critical for trees less than 5 years in the ground.
Drip Irrigation
Drip irrigation typically has more lenient restrictions than lawn sprinkler systems. If you have drip on beds and trees, you may be able to water them more frequently than the lawn. Verify the specific rules for drip in your stage.
Hand Watering
Hand watering with a hose has different rules from sprinkler systems. Use it for high-value plants and small targeted areas where you cannot afford dormancy or damage.
What Not to Do
Do Not Water on Non-Designated Days
SAWS issues fines for violations, and fines escalate for repeat violations. The lawn benefit you might gain is not worth the financial penalty.
Do Not Run Sprinklers During Forbidden Hours
Restrictions often limit times to early morning and late evening to reduce evaporation. Running outside those hours wastes water and violates the rules.
Do Not Over-Fertilize During Drought
Heavy nitrogen on a water-stressed lawn produces growth the lawn cannot support. Avoid aeration during peak heat or drought — wait for cooler conditions or restriction lift.
Do Not Panic About Appearance
Going semi-dormant is protective, not catastrophic. Avoid ignoring the lawn entirely — even minimal supplemental watering during restrictions helps the lawn survive.
After Restrictions Lift & Long-Term Resilience
Returning to Normal Watering
When restrictions lift, return gradually rather than dumping water immediately. Start with two cycles per week at normal volumes. Apply a light moderate-nitrogen fertilizer with potassium to support recovery. Full recovery typically takes 4 to 8 weeks.
Building Drought Resilience Over Time
Switch to more drought-tolerant grass species (Bermuda is more drought-tolerant than St. Augustine). Improve soil organic matter through annual compost topdressing. Install high-efficiency rotor nozzles and drip in beds. Plant trees and shrubs that thrive in our climate naturally. Each practice pays back across decades.
How Drought Recovery Compounds
Lawns managed well through one drought enter the next year with healthy crown reserves and recover quickly. Over 5 to 10 years across multiple drought cycles, the difference between proper restriction management and panicked overreaction is dramatic.
Frequently Asked Questions
How do I know when restrictions change?
SAWS announcements via local news, their website, and email notifications if you sign up. Restrictions can change quickly when drought conditions shift.
Can I use rainwater I collected myself?
Yes. Captured rainwater is not subject to SAWS restrictions. Rain barrels and cisterns are legitimate sources during any restriction stage.
What if my lawn is dying despite following restrictions?
Lawns on thin or compacted soil, recently installed lawns, and lawns in particularly hot exposures may struggle more. Consider whether the grass species fits your conditions, and consider fall renovation if damage is severe.
Will SAWS check my watering?
SAWS does send inspectors during restrictions. Violations result in warnings first, then escalating fines. Neighbors can also report violations.
